I’ve added the final topic of the PROC SQL course in the SAS course (in the SAS Programming Forum), and it describes some of the limitations and differences between the SQL language in PROC SQL and the ANSI (American National Standards Institute) guidelines for SQL.
I’ve also added, for those who don’t want to follow the course but would prefer to read the course notes, a copy of course notes as a downloadable PDF ebook, and have published Android ebook apps with the same content on Google Play and Amazon Appstore.
As other SAS courses are finalised I will be publishing them as PDF ebooks and Android apps too.
